copilot-customization

VS Code Copilot customization uses different mechanisms based on task scope: instructions for guidelines, prompt files for reusable templates, custom agents for scoped workflows, skills for specialized capabilities, and MCP servers for external data. This skill helps you select the right format and explains how to author it.

To create a custom Copilot skill, author a compliant SKILL.md file with correct discovery frontmatter and progressive loading rules. This ensures your skill loads properly and aligns with repository-specific reference guidance for VS Code conventions.

Use an MCP server when your Copilot workflow requires external data connectivity or tool integration, and choose a custom agent for scoped, workspace-specific automation tasks. This skill compares these mechanisms to help you pick the right format.

Your Copilot skill may not be loading due to non-compliant SKILL.md frontmatter, missing discovery fields, or progressive loading rule violations. This skill diagnoses the configuration error and identifies the relevant reference material to fix it.

You need hooks or plugin packaging when distributing Copilot customizations across multiple repositories or team environments. This skill explains when to package extensions as plugins versus using local instructions or prompt files.

Yes, you can standardize Copilot extensions by using compliant SKILL.md files, consistent discovery frontmatter, and plugin packaging. This skill helps teams reduce misconfigured files and keep workspace automation aligned with VS Code conventions.
